Abstract
A printing method for ink jet printing on a recording substrate in which a column of N dot forming nozzles for projecting ink onto a printing area are arranged, wherein N is an integer greater than 2. The column of dot forming nozzles are moved horizontally across the printing area and in each column of the printing area the printhead deposits one or more dots from a subgroup of S dot forming nozzles, wherein S is an integer of from 1 to about N−1. In each column of the printing area, not more than every Gth nozzle deposits a dot and a single nozzle deposits a dot not more than every Gth column, wherein G is an integer from 1 to about S. The subgroup of S dot forming nozzles is shifted vertically among the N dot forming nozzles in at least two adjacent columns according to a predetermined pattern. The recording substrate is vertically advanced in a first direction by a height of about Q nozzles, wherein Q=(S/G). Printer apparatuses including the printing method.
